 · Three successive sets of plants were grown for altogether 23 weeks without further addition of K. The K bound in K‐feldspar seemed to be nearly unavailable for the plants during the experimental period. However considerable amounts of K were taken up from rocks and tailings containing nepheline and/or biotite as their main K‐bearing minerals.

 · It has two operating plants at its Blue Mountain deposit (the Havelock deposit) which is located about 175 kilometres northeast of Toronto Ontario. Production of marketable Nepheline Syenite was estimated to be about 710 000 tons in 2004. The major use of the Nepheline taken from this quarry is for ceramics such as toilet bowls and sinks.

Feldspar and Nepheline Synenite (Advance Release)

 · Nepheline syenite is an essentially quartz-free igneous rock composed of alkali feldspars and nepheline which is a feldspathoid mineral that forms in place of alkali feldspars because the magma (melt) was deficient in silica. Nepheline syenite has many uses similar to those of alkali feldspar.
